To quote Walt Disney regarding Disneyland,
"Your dead if you aim only for kids. Adults are only kids grown up, anyway."
Kids love the Dumbo spinners, their parents and adults enjoy (not just tolerate) the nice atmosphere in Fantasyland. Adding some magic to the queue that everybody can participate in would have been better, IMHO.
Walt didn't underestimate the intelligence of children,
"Adults are interested if you don't play down to the little 2 or 3 year olds or talk down. I don't believe in talking down to children. I don't believe in talking down to any certain segment. I like to kind of just talk in a general way to the audience. Children are always reaching."
The new Dubmo queue is NOT interactive and with cheap decorations and standard McDonald's play equipment lightly themed doesn't help kids explore their imagination or reach to enjoy something a little more complex.
Walt would have loved all of the new computer technology, and he would have wanted to build something interactive and totally in the queue. In the video one kid steps on a "trampoline", which is just a plastic board and a couple seconds later it lights up. Weird and kinda pathetic if that's all they can come up with. To quote Walt again,
"It's no secret that we were sticking just about every nickel we had on the chance that people would really be interested in something totally new and unique in the field of entertainment."
